ADJUSTABLE BEAM BEARINGS Filed Oct. 4, 1952 INVENTOR. JESSE GORDON SM! TH BY mfdkmi ATTORNEY United States Patent 1 2,730,413 ADJUSTABLE BEAM BEARINGS .l'esse Gordon SmitlnLanett, Ala, assignor to Batson- Cook Company, West Point, Ga, a corporation of Georgia Application October 4, 1952, Serial No. 313,123 1 Claim. (Cl. 308-24) This invention relates to bearings and more particularly to adjustable beam bearings.

In the past, looms have been constructed with the yarn beam bearings in a permanently fixed position for a particular yarn beam diameter which in turn fixed the size of the yarn beam gear diameter, the driving pinion gear diameter and the roll setting. This would probably be an ideal arrangement if all yarn beams were the same but the textile industry, as a whole, has made little or no attempt at standardizing the size of the yarn beam or the other components such as the yarn beam gear, the driving pinion gear and the roll setting in general. These variations are undoubtedly unavoidable in view of the many different operations for which they must be built but they constitute a major problem to the loom operators who must cope with the varying sizes of yarn beams and the other components.

To'use yarn beams of varying size, the loom operator must either remake the yarn beam bearing to enable the loom to utilize the new size or change the position of other parts of the loom to prevent their interference with the odd sized yarn beam. It can be seen that this procedure of remaking the yarn beam hearing or relocating other parts of the loom to match the various size yarn beams results in additional expense both in man hours and in the time the loom is inoperative while these necessary changes are being made.

It is therefore an object of my invention to provide a yarn beam hearing which is easily adjusted for any diameter yarn beam, yarn beam gear or driving pinion gear.

Another object of my invention is to provide an adjustable yarn beam hearing which is adaptable to any diameter yarn beam without repositioning any other parts of the loom to compensate for the varying sizes of yarn beams.

Another object of my invention is to provide an ad; justable yarn beam bearing which may be readily installed on any standard loom with a minimum amount of alteration.

A still further object of my invention is to provide an adjustable yarn beam bearing that is simple and inexpensive to manufacture and durable in construction.

Other and further objects and advantages of my invention will become apparent from the following description of an embodiment of my invention when taken in conjunction with the accompanying drawings in which like characters of reference designate corresponding parts throughout the views, and wherein:

Fig. 1 is a front elevation of an embodiment of my invention as used with a loom.

Fig. 2 is an isometric view of my device.

Fig. 3 shows fastening means for my device.

Referring now in detail to the drawings in which like numerals refer to corresponding parts throughout and in which the numeral refers to a yarn beam which is supported by the yarn beam shaft 11 to which the yarn beam gear 12 is securely fastened. Yarn beam gear 12 enmeshes with and is driven by the pinion gear 13 which is journaled in the loom frame 14. The stationary supporting arm 15 is securely fastened to loom frame 14 by means of bolts 16 and is correctly and accurately positioned by means of flange 17 and lug 18. The serrated portions 19 and 19' are slidably engaged with the serrated portion 2%) of the adjustable supporting member 21 which is held in a pro-selected position by means of bolts 22 which pass through the slot 23 in the stationary supporting member 15 and through slots 24 and 24' in the adjustable supporting member 21. The top portion of the adjustable supporting member 21 is concaved to form lower bearing 25 which is complementary to detachable top bearing 26. Projecting up from hearing 26 is a flange 27 which is contiguous with a flange 23 extending up from supporting member 21. A fastening means such as bolt 29 passes through appropriate slots 27', 28 in flanges 27 and 28, respectively, to position bearing 26 with respect to bearing 25 and thereby journal the yarn beam shaft 11.

Assuming now that the adjustable beam bearing has been installed on a loom and it is desirous to change the position of the bearing to compensate for a different sized yarn beam, yarn beam gear or driving pinion gear. The bolts 22 are loosened and the adjustable supporting arm 2.1 is allowed to slide towards or away from the driving pinion gear 13 until the yarn beam gear 12 enmeshes with the pinion gear 13. if any part of the loom happens to interfere with the movement of the yarn beam gear 12, then the adjustable supporting member 21 is repositioned vertically by engaging the serrated portion 20 at a diiierent group of serrations with respect to the serrated portions 19 and 19' of the stationary supporting arm 15. It is to be remembered that the increments of vertical adjustment are governed by the size of the serrations and therefore may be varied for the various types of looms that may be encountered.

While I have shown and described a specific embodiment of my invention, it is to be understood that many variations may be made by those skilled in the art without departing from the scope of my invention as defined by the appended claim.

I claim:

In an adjustable beam bearing for attachment to a loom frame, a stationary supporting arm provided with a lug and a positioning flange for removably positioning said arm on said frame, said flange being constructed to overlie a horizontal portion of said frame and said lug being constructed to abut a vertical portion of said frame, said arm having longitudinal serrations on one face thereof and a longitudinal slot therein, an adjustable supporting member having serrations on one face thereof adjustably engaged with said serrations on said supporting arm, said adjustable supporting member being provided with a plurality of slots at substantially right angles to said slot in said stationary supporting arm, said adjustable supporting member being adjustably fastened to said stationary supporting arm by fastening means passing through the said slots in said adjustable supporting member and the said slot in said stationary supporting arm, a bearing member carried by said adjustable supporting member, a flange on said adjustable supporting member, a complementary bearing member positioned adjacent said first mentioned bearing member, a flange on said complementary bearing member, said complementary bearing member being adjustably retained in position adjacent said first mentioned bearing member by fastening means passing through the flange on said adjustable supporting member and the flange on said complementary bearing member.
